Having issues installing the Patch...

[Ultimastrike]

Hey. I'm trying to get back into the game but the patch isn't working because I downloaded the ZIP version. Also, whenever I'm installing the patch when it gets to this specific packet "FileName:Patch00000558.pak" the client installing the patch crashes due to a data error. Any fixes?

I had a similar problem, I ran the updater as an admin and it patched correctly. Been working fine since.
